Professionals Asked We Listened

"I have absolutely never been this happy about my guitar tone. The GSP1101 possesses all of the great Clean and Overdrive amp tones that I have always wanted for the stage and in the studio. Extremely versatile, yet very easy to quickly find your way around to design all of your dream presets. The results speak very clear with the GSP1101 pre amp and i have a strong feeling that a lot of players will soon agree!" Glen Drover - Megadeth

The GSP1101 is the new paradigm in preamp/processors. We looked at the needs of the professional guitarists who already get their core tone with their amps, guitars, and fingers. The pros wanted to do everything from just adding a few effects to their existing tone to creating entirely new sounds with a single rack-mount preamp/processor. One concern they had in common; "Don't take over my rig like other preamps do." This required a whole new approach in design.

The GSP1101 answers the professional guitarist's call for "tone preservation" by incorporating the flexibility to be easily integrated into any rig and configured to work the way you want it. DigiTech's unique Setup Wizard guides you through the steps to optimize the GSP1101 to fit your needs.

The GSP1101 not only preserves your tone, but it gives you access to a vast array of over 120 different models, from stompbox overdrives, preamps, and amps, to studio quality effects including luscious Lexicon® reverbs and unique products like DigiTech's Whammy®. So many sounds, so little time…

Don't sell yourself short or compromise your tone. You've got your sound; now get more out of your rig with the GSP1101.
